Abstract

The LILI-II keystream generator is a LFSR based synchronous stream cipher with a 128 bit key. LILI-II is a specific cipher from the LILI family of keystream generators, and was designed with larger internal components than previous ciphers in this class, in order to provide increased security. The design offers large period and linear complexity, is immune to currently known styles of attack, and is simple to implement in hardware or software. The cipher achieves a security level of 128 bits.
